If before 100 days, adjustments can still be made. After 100 days, adjustments are difficult.

• Before 100 days, calculate feed intake to see if it is normal; if not, treat. At the same time, adjust feed formula.
• Add 1 hour of light at 12 midnight to promote feeding, regular weighing is very important.
• Increase feeding frequency, feed less but more often.

Overweight:

Exceeding standard weight by +10% or more, each hen consumes 7 jin more full-price feed per production cycle than normal hens, production performance does not improve, later mortality rate increases by 1%.

Underweight:

Prone to egg retention at onset of lay, slow peak climb. Egg weight not meeting standards. High later mortality, light weight of culled hens.

Causes of juvenile chickens not meeting standards:

Disease Factors

Chick adenogastritis, coccidiosis, mycotoxins, synovial arthritis diseases affect flock growth rate. Especially adenogastritis and synovial arthritis affect vitamin absorption and utilization, affect molting speed, thereby hindering flock growth.

Management Factors

Unreasonable flock density, no timely grouping. Hazards of juvenile chickens not meeting standards: Body weight and shank not meeting standards directly affect laying hens’ onset of lay time, climbing speed, and peak maintenance duration. Light weight, underdeveloped shank: Prone to prolapse at onset of lay, light egg weight, prone to paralyzed chickens.

Overweight

Many double-yolked eggs after onset of lay, high feed intake, high feed-egg ratio.drop syndrome, salmonellosis, E. coli disease, etc., making eggshells pale, uneven thickness, lighter color.
